Only Change Is Consistent
The only thing that's ever consistent in life is change. From the physical world to your mental world, everything is changing over time. You are no longer the person you were 10 years ago, your habits and preferences have changed thus far, what makes you think they won't change again in the next 10 years?
Consistency is cool and all, but it's a bit like clinging to certainty. We want things to stay the way they are, we don't like uncertainty or unexpected changes. But that's not how things work around here. The only thing we can expect to be certain or consistent is change.
